How do I include a loop while writing out a function

function [mean,std] = stats(x)

      A = (1:1:x);

      B = numel(A);

      C = sum(A);

      D = (C/B);

      disp(mean)

   end

What would the loop calculate?

By the way, it is a bad idea to use "mean" as the name of a variable, as "mean" is the name of a MATLAB routine. You are going to confuse other people and yourself when you use a variable name that is the same as the name of a common routine.

As suggested by Walter in one of the comments, it is probably the best to replace variable name 'mean' with a new name since MATLAB has in-built function named "mean". In your example, you can use a for loop to perform the mean computation using following code:

   function [mn,std] = find_mean(x)
          A = (1:1:x);
          sum = 0;
          num = numel(A);
          for i=1:num
              sum = sum + A(i);
          end
          mn = sum/num;
          disp(mn);
    end

However, it is recommended to use MATLAB in-built functions such as "sum", "mean" and so on whenever possible for efficient computations. I hope this answers your question.
